The Microchip USB2422 hub is a low-power, single
transaction translator, hub controller IC with two downstream
ports for embedded USB solutions. The hub
controller can attach to an upstream port as a Hi-Speed
and Full-Speed hub or as a Full-Speed only hub. The
hub supports Low-Speed, Full-Speed, and Hi-Speed
(when configured as a Hi-Speed hub) downstream
devices on the enabled downstream ports.
All required resistors on the USB ports are integrated
